Service Level Agreement

Effective Date: August 15, 2013

This Firebase Service Level Agreement ("SLA") is a policy governing the use of Firebase cloud-based services
("Firebase Services") under the terms of the Firebase Terms of Service (the "Terms of Service") between
Firebase, Inc. ("Firebase", "us" or "we") and users of Firebase Services ("you"). This SLA applies
separately to each account using Firebase Services. Unless otherwise provided herein, this SLA is subject
to the terms of the Terms of Service. Firebase reserves the right to change the terms of this SLA
in accordance with the Terms of Service.

1. Service Commitment

Firebase will use commercially reasonable efforts to make Firebase instances available with a
Monthly Uptime Percentage (defined below) of at least 99.95%, in each case during any monthly billing cycle
(the "Service Commitment"). In the event Firebase does not meet the Service Commitment, you will be
eligible to receive a Service Credit as described below.

2. Definitions

The following capitalized terms shall be given the meaning set forth below:

"Monthly Uptime Percentage" is calculated by subtracting from 100% the percentage of continuous 5 minute periods
during the month in which a Firebase instance was in a state of "Unavailable." Monthly Uptime Percentage
measurements exclude downtime resulting directly or indirectly from any Firebase SLA Exclusion (defined below).

"Unavailable" and "Unavailability" means when a running Firebase instance has no external connectivity.

A "Service Credit" is a dollar credit, calculated as set forth below, that we may credit back to an eligible account.

3. Service Commitments and Service Credits

Service Credits are calculated as a percentage of the total charges paid by you (excluding one-time payments
such as upfront payments) for a Firebase instance for the monthly billing cycle in which the Unavailability
occurred in accordance with the schedule below.

Monthly Uptime Percentage

Service Credit Percentage

Less than 99.95% but equal to or greater than 99.0%

10%

Less than 99.0%

30%

We will apply any Service Credits only against future Firebase payments otherwise due from you.
At our discretion, we may issue the Service Credit to the credit card you used to pay for the billing
cycle in which the Unavailability occurred. Service Credits will not entitle you to any refund or other
payment from Firebase. A Service Credit will be applicable and issued only if the credit amount for
the applicable monthly billing cycle is greater than one dollar ($1 USD). Service Credits may not be
transferred or applied to any other account. Unless otherwise provided in the Terms of Service, your
sole and exclusive remedy for any unavailability, non-performance, or other failure by us to provide
Firebase Services is the receipt of a Service Credit (if eligible) in accordance with the terms of this SLA.

4. Credit Request and Payment Procedures

To receive a Service Credit, you must submit a claim by sending an email to firebase-support@google.com.
To be eligible, the credit request must be received by us by the end of the second billing cycle
after which the incident occurred and must include:

i. the words "SLA Credit Request" in the subject line;

ii. the dates and times of each Unavailability incident that you are claiming;

iii. the affected Firebase instance urls; and

iv. your request logs that document the errors and corroborate your claimed outage (any confidential or sensitive information in these logs should be removed or replaced with asterisks).

If the Monthly Uptime Percentage of such request is confirmed by us and is less than the Service Commitment,
then we will issue the Service Credit to you within one billing cycle following the month in which your
request is confirmed by us. Your failure to provide the request and other information as required
above will disqualify you from receiving a Service Credit.

5. Firebase SLA Exclusions

The Service Commitment does not apply to any unavailability, suspension or termination of
Firebase Services, or any other Firebase or Firebase Services performance issues: (i) caused
by factors outside of our reasonable control, including, without limitation, any force majeure
event or Internet access or related problems beyond the demarcation point of Firebase Services or
its direct hosting subcontractors (i.e beyond the point in the network where Firebase maintains
access and control over the Firebase Services); (ii) that result from any actions or inactions of
you or any third party (other than Firebase’s direct hosting subcontractor); (iii) that result from your equipment, software or other technology
and/or third party equipment, software or other technology (other than third party equipment within
our direct control); (iv) that result from any scheduled maintenance; or (vi) arising from our
suspension and termination of your right to use Firebase Services in connection with any breach by
you of the Terms of Service or otherwise in accordance with the Terms of Service
(collectively, the "Firebase SLA Exclusions"). If availability is impacted by factors other than those used in
our Monthly Uptime Percentage calculation, then we may issue a Service Credit considering such factors at our discretion.
